The Uric Acid Serum Test measures the amount of uric acid in your blood. Elevated uric acid levels can indicate conditions like gout, arthritis, or kidney disease. High uric acid can lead to the formation of urate crystals, which cause joint inflammation in gout. On the other hand, very low levels of uric acid may signal kidney dysfunction or other related issues. This test is particularly helpful in diagnosing and monitoring gout and kidney disorders.
